Unreal Engine + Perforce (Helix Core) + WireGuard VPN Setup

🎮 Unreal Engine + Perforce (Helix Core) + WireGuard VPN Setup

Guide to setting up Unreal Engine collaboration with Perforce (Helix Core) over a WireGuard VPN, using an Ubuntu/Debian server and Windows clients.

A complete guide to setting up a secure collaborative workflow for Unreal Engine development using:

✅ Ubuntu/Debian Server (Perforce + WireGuard)
✅ Windows Clients (Unreal Engine + P4V)
✅ Secure LAN-like connectivity via WireGuard VPN

🔒 Security & Licensing Notice

Make sure to secure your server:
- Use strong SSH passwords or key authentication
- Only expose necessary ports (e.g., VPN and Perforce)
- Restrict access to VPN IPs via firewall
Regularly update your system and packages to avoid vulnerabilities.
✅ Perforce (Helix Core Server) Please review the Perforce licensing terms.

🚨 Always follow best practices for securing infrastructure, especially if hosting remotely.

⚙️ 1. Setup WireGuard VPN

🖥️ On Ubuntu/Debian Server

Console Output

	sudo apt update
	sudo apt install wireguard
	wg genkey \| tee privatekey \| wg pubkey > publickey

Create /etc/wireguard/wg0.conf:

Console Output

	[Interface]
	Address = 10.66.66.1/24
	PrivateKey = <server-private-key>
	ListenPort = 51820
	SaveConfig = true

Enable IP forwarding:

Console Output

	echo “net.ipv4.ip_forward=1” \| sudo tee -a /etc/sysctl.conf
	sudo sysctl -p

Start the VPN:

Console Output

	sudo systemctl enable wg-quick@wg0
	sudo systemctl start wg-quick@wg0

💻 On Windows Clients

Install WireGuard for Windows and use:

Console Output

	[Interface]
	PrivateKey = <client-private-key>
	Address = 10.66.66.2/32

	[Peer]
	PublicKey = <server-public-key>
	Endpoint = your.server.ip:51820
	AllowedIPs = 10.66.66.0/24
	PersistentKeepalive = 25

✅ Test: ping 10.66.66.1

📦 2. Install Perforce (Helix Core Server)

On Ubuntu/Debian Server

Console Output

	wget -qO – https://package.perforce.com/perforce.pubkey \| sudo apt-key add –
	echo “deb http://package.perforce.com/apt/ubuntu jammy release” \| sudo tee /etc/apt/sources.list.d/perforce.list
	sudo apt update
	sudo apt install -y helix-p4d

Create required directories:

Console Output

	sudo mkdir -p /opt/perforce/metadata /opt/perforce/depot
	sudo useradd -r -s /bin/false perforce \|\| true
	sudo chown -R perforce: /opt/perforce

Initialize the database:

Console Output

sudo -u perforce /usr/sbin/p4d -r /opt/perforce/metadata -J journal -xi

Create systemd service:

Console Output

# /etc/systemd/system/perforce.service
[Unit]
Description=Helix Core Perforce Server
After=network.target
[Service]
User=perforce
ExecStart=/usr/sbin/p4d -r /opt/perforce/metadata -p 1666 -L /opt/perforce/metadata/log -J /opt/perforce/metadata/journal
Restart=always

Enable and start:

Console Output

	sudo systemctl daemon-reexec
	sudo systemctl enable perforce
	sudo systemctl start perforce

Install CLI (optional):

Console Output

	wget https://cdist2.perforce.com/perforce/r24.1/bin.linux26x86_64/p4
	chmod +x p4
	sudo mv p4 /usr/local/bin/

👤 3. Create User, Depot, and Workspace

On Ubuntu/Debian Server

Console Output

	p4 -p 127.0.0.1:1666 user
	p4 passwd
	p4 depot UEProject

In P4V (Windows)

Workspace Name: client1_ue
Root: D:UnrealProjectsMyGame
View://UEProject/… //client1_ue/…

🖥️ P4V: Installing & Using the Perforce GUI

🧩 What is P4V?

P4V is the official graphical client for Perforce. It allows users to:

Create and manage workspaces
View changelists and depot structure
Add, check out, and submit files
Visualize file history and diffs

🛠️ Installing P4V on Windows

Download P4V from the official Perforce website:👉 https://www.perforce.com/downloads/helix-visual-client-p4v
Install and launch the client.
On first launch, provide your server info:


Server	10.66.66.1:1666
Username	your Perforce user
Workspace	(leave blank initially)

⚠️ Known Issue: Large Unreal Projects May Cause Freezes

When using the “Add Files Wizard” in P4V on large Unreal projects:

P4V may freeze or crash (“Not Responding”) due to scanning thousands of files
Especially common if temporary folders like Binaries/, Intermediate/, or Saved/ are included

✅ Safer Alternative: Use p4 CLI for Initial Add

If P4V becomes unresponsive:

Open a terminal (PowerShell or CMD)
Set environment variables:

Console Output

	p4 set P4PORT=10.66.66.1:1666
	p4 set P4USER=your_username
	p4 set P4CLIENT=your_workspace

🧩 4. Unreal Engine Integration

Open the .uproject inside the workspace root
Go to File → Source Control → Connect to Source Control
Choose Perforce and fill:


Server	10.66.66.1:1666
Username	Your Perforce user
Workspace	client1_ue

Accept → green check ✅ appears
Add files:
- ✅ .uproject, Config/, Content/, Source/
- ❌ Skip: Binaries/, Intermediate/, Saved/
Submit:

Console Output

File → Submit to Source Control

📄 Recommended .p4ignore

Place in project root:

Console Output

	Binaries/
	DerivedDataCache/
	Intermediate/
	Saved/
	.vs/
	.vscode/
	*.sdf
	*.suo
	*.user
	*.log

Then:

Console Output

	p4 add .p4ignore
	p4 submit -d “Add ignore file”

✅ You’re Ready!

You now have:

🔒 VPN access to Perforce
🛠️ Source controlled Unreal Engine project
📡 Remote collaboration with low-latency file access

🔁 Workflow Tips
